Privacy Policy

1. Overview

ConceptViz (“we,” “us,” or “our”) helps U.S. teachers generate classroom-ready diagrams. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using ConceptViz, you consent to the practices described below.

Effective Date: November 28, 2025

2. Information We Collect

Account Information

Name and email address
School, district, or subject focus (if provided)
Authentication tokens for sign-in providers

Billing Information

Subscription tier and payment status
Billing address when required by regulation
Transaction IDs from our payment processor (we never store full card numbers)

Usage & Generation Data

Prompts and settings you submit to generate diagrams
Generated images and metadata (subject tags, grade level) needed to deliver the Service
Limited log data to troubleshoot errors, combat abuse, and improve quality

Technical Data

Device type, browser, and operating system
IP address and approximate region
Session cookies or secure tokens to keep you logged in

We do not intentionally collect student names, grades, or other student PII. Do not include such data in prompts.

3. How We Use Information

We process your data to:

Provide, personalize, and operate the Service
Track credit usage and enforce plan limits
Respond to support requests and send service-related notices
Detect fraud, abuse, or policy violations
Comply with legal obligations (tax, accounting, law enforcement requests)

We may aggregate anonymized usage statistics to understand lesson trends and prioritize curriculum categories. Aggregated data cannot be traced back to a specific teacher.

We share information only with:

Payment processors: To collect subscription fees and manage invoices
Authentication providers: To log you in securely
Infrastructure partners: To host the application, store images, and run AI workflows. These partners process prompts and images solely to deliver ConceptViz features and may not use them to train their own public models.
Professional advisors or authorities: When required by law or to enforce our rights

We do not sell educator data or student-related information.

5. Data Retention

Account data persists while your account remains active.
Generated diagrams are stored for up to 90 days for paid accounts (shorter for free accounts) unless you delete them earlier.
Billing records are retained for at least seven years to satisfy U.S. tax rules.
Log data is typically retained for 30–90 days unless needed for security investigations.

You may email contact@conceptviz.app to request deletion of your account and associated content. Some records (like invoices) must remain for compliance purposes.

6. Security

We use HTTPS, role-based access, encryption at rest for stored diagrams, and routine audits to safeguard your data. No system is perfectly secure, so please notify us immediately if you suspect unauthorized access.

7. Your Choices

Access & Correction: View or update account details in your settings.
Data Export: Request a copy of your diagrams and prompt history for a given time range.
Deletion: Request account deletion by emailing contact@conceptviz.app.
